I golf a lot, and this seems like A "No kidding..." type of statement to me.<p>Birdie putts are less common, even for great golfers, and so when it comes up everyone tends to put a little bit more pressure on themselves, consciously or unconsciously, to capitalize on the birdie putt.<p>Even when you have a short one (less than 5 feet) you friends will say "Oh, don't miss..." etc.
